今天在做springboot整合成springCloud并注册到consul中时，发现若注册到consule中成功 则不能启动swagger，且不能提供任何API服务，要是能提供API服务则不能注册到consule中，并报错“
Spring MVC found on classpath, which is incompatible with Spring Cloud Gateway at this time. "+
"Please remove spring-boot-starter-web dependency
”
分析了一下，发现在如下代码中会报这个log信息
@Configuration
@AutoConfigureBefore(GatewayAutoConfiguration.class)
public class GatewayClassPathWarningAutoConfiguration {
private static final Log log = LogFactory.getLog(GatewayClassPathWarningAutoConfiguration.class);
private static final String BORDER = "\n\n**********************************************************\n\n";
@Configuration
@ConditionalOnClass(name = "org.springframework.web.servlet.DispatcherServlet")
protected static class SpringMvcFoundOnClasspathConfiguration {
public SpringMvcFoundOnClasspathConfiguration() {
log.warn(BORDER+"Spring MVC found on classpath, which is incompatible with Spring Cloud Gateway at this time. "+
"Please remove spring-boot-starter-web dependency."+BORDER);
}
}
@Configuration
@ConditionalOnMissingClass("org.springframework.web.reactive.DispatcherHandler")
protected static class WebfluxMissingFromClasspathConfiguration {
public WebfluxMissingFromClasspathConfiguration() {
log.warn(BORDER+"Spring Webflux is missing from the classpath, which is required for Spring Cloud Gateway at this time. "+
"Please add spring-boot-starter-webflux dependency."+BORDER);
}
}
}
最终，我们分析是swagger启动时所要的jar包和springCloud有所冲突，修改我们的POM文件如下，主要是版本的问题：
发现consul 1.2版本需要和SpringCloud的Finchley版本才能整合
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.3.RELEASE</version>
